Abstract

　本発明は、内燃機関の制御装置に関し、燃料改質触媒の劣化を確実に抑制することを目的とする。 　ＥＧＲ通路３２，３６と、ＥＧＲガス中に改質用燃料を噴射する改質用燃料噴射装置３４と、燃料改質触媒２６とを備える。燃料改質触媒２６は、排気通路２８を通る排気ガスの熱を受熱してＥＧＲガスと改質用燃料とを改質反応させることにより、ＥＧＲガスおよび改質用燃料を、可燃ガスを含む改質ガスに転換する。ＥＣＵ５０は、運転条件急変状態であると判定した場合には、改質用燃料噴射装置３４からの燃料噴射量を減量または禁止する。これにより、燃料改質触媒２６への燃料付着や酸素の流入を抑制し、燃料改質触媒２６での燃料の酸化反応（燃焼）を回避する。
